Man, you just can't go wrong. Land will at least keep its value if you buy it cheap. Just be sure to have money enough to buy food if you need. Lots of simple people in the world lives their whole lives in the country. In small cities is much easier to make friends. Growing food is not rocket science. I would recommend starting trying a little bit of it now, if possible. It could be some plants on pots like Jacob is doing. You will learn that it is not hard work. Growing food small scale for a family is easy and fun. My grandma still grows her vegetables and is 85 years old already. You also don't have to grow everything, do what you can. What is hard is getting money from selling food, because of the competition of low price of agrobusiness. But if you have your needs covered by invested money AND you can try to cover your needs from nature, it is a pretty fail safe situation. You are relying on social capital (money) or individual capital (skills) and nature. Double coverage.
In fact, that is almost exactly my plan, except that I am in another part of the world. What I am doing is that I am stocking money for FI and after that will stock a little more for buying the land. I am not counting on the food I will grow. If you can, try to buy some land where you could get wood for construction, building furniture and for a wood stove.
You don't have to pay for garbage collection as you will compost your organic waste, and recycle most of the rest. The best fire insurance is a well built house and you having the skill to build another one if needed be. You can repair your home using mostly materials you get from nature. You can make bricks from earth. You can build with wood. The rest you buy, you will not be able to stop getting money. Any skill you have yield you some money. If you need some more, you just freelance a little bit. If you have money for the basics, the rest is easier.
Health insurance is a more polemic issue but I say that you just can not insure you health by paying money. It is not possible. Some things money will not buy. Like a black belt and your health. So a health insurance plan does not insure health. It would be better if called a disease insurance plan, as in most cases it will be useful only if you do not take good care of your health. For those thinking about accidents and some other extreme situation not related to health (but related to lifestyle, but granted, you can not avoid everything), there are plans that cover only very big expenses, not the small ones, and that are said to be much cheaper. I do not know about the availability of those in your place.
